摘要
提出计算双层土壤复合接地网接地电阻的新解析方法。经过一系列推导验证表明:新解析法与计算机数值算法结果吻合较好,且公式的物理意义清晰,计算误差小,使用方便。
A new analytic method for grounding resistance of compound grounding grids in two-layer soil is deduced in this paper. The results of verifying calculation show that it agrees with the results of computer numerical arithmetic, and the new analytic formula has the advantages of clear physical meaning, small computational error and easy use.
